【摘要】：坐落于上海的金茂大厦、上海环球金融中心和上海中心大厦三幢闻名世界的超高层建筑的基础均为补偿深埋桩筏基础。在补偿深埋桩筏基础设计中如何充分考虑补偿基础的优越性,如何考虑深埋基础的抗风能力,是值得研究的问题。利用高层建筑与地基基础共同作用的分析方法,结合统计-经验公式对该三幢大楼的桩筏深基础进行了再分析。通过再分析在节约相当数量的桩之后,其地基承载力和变形仍然能够满足设计要求。同时在再分析中进一步探讨优化设计的能力,论证地下连续墙可以分担相当数量的荷载。相关案例的再分析对进一步完善补偿深埋桩筏基础设计理论提出建议,可为国家节省大量投资。
[Abstract]:Jinmao Tower, located in Shanghai, The foundation of the three world-famous super high-rise buildings in Shanghai Global Financial Center and Shanghai Center Building is the foundation of the compensation deep buried pile raft foundation. How to fully consider the superiority of the compensation foundation in the design of the compensation deep buried pile raft foundation, How to consider the wind resistance of deep buried foundation is a problem worth studying. The deep foundation of the pile-raft of the three buildings is reanalyzed by combining the statistical and empirical formula. After saving a considerable number of piles, The bearing capacity and deformation of the foundation can still meet the design requirements. It is demonstrated that the underground diaphragm wall can share a considerable amount of load. The reanalysis of relevant cases puts forward some suggestions for further improving the design theory of deeply buried pile raft foundation, which can save a large amount of investment for the country.
